Single corrugated expansion joint

Universal corrugated compensator (expansion joint), consisting of a corrugated pipe and a structure, it absorbs the axial displacement of the pipeline and a small amount of lateral and angular displacement through the flexible deformation of the corrugated pipe, and is connected at both ends or directly welded with the pipe connection, or The welded flange is then connected to the pipe flange. The small tie rod on the compensator is used as a rigid support during transportation or as a product and deformation adjustment, and cannot be used as a tension rod for balancing the pressure and thrust. This type of structure is simple and the cost is low, so it should be considered first where the pipeline is available.

The axial metal bellows expansion joint produced by our company adopts the optimized design of the American EJMA standard. While meeting the domestic market demand, the products are exported to 22 foreign countries. It is widely used in the connection of aerospace, navigation, petrochemical, smelting, power plants, information industry, industrial equipment manufacturing and engineering pipelines, effectively ensuring the high safety of pressure pipelines when transporting various harmful, toxic, flammable and explosive media. performance, to avoid leakage pollution causing environmental pollution such as oceans, sky, factories, etc. Its product features are high temperature resistance, high pressure resistance, corrosion resistance, fatigue resistance and wear resistance.

Technical parameters of JDZ corrugated expansion joints:

The axial internal pressure bellows compensator uses the effective expansion and contraction deformation of its working body bellows to absorb the dimensional changes of pipelines, pipes, containers, etc. caused by thermal expansion and contraction, or to compensate for the axial direction of pipelines, pipes, containers, etc. , lateral and angular displacements. JDZ type axial internal pressure corrugated compensator uses the expansion and deflection of the main elastic element of the corrugated pipe to stop the displacement compensation of the pipeline line. The compensation amount is large and the elasticity is good. The product is suitable for conveying seawater, fresh water, cold and hot water. , drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, waste oil, air, gas and other media.

1. Compensate the axial, lateral and angular thermal deformation of the absorption pipeline.

2. The expansion and contraction amount of the corrugated compensator is convenient for the installation and disassembly of the valve pipeline.

3. Absorb equipment vibration and reduce the impact of equipment vibration on the pipeline.

4. Absorb the deformation of the pipeline caused by earthquake and subsidence.
